The CSS.escape() static method returns a DOMString containing the escaped string passed as parameter, mostly for use as part of a CSS selector.

Syntax

escapedStr = CSS.escape(str);

Parameters

str
The DOMString to be escaped.

Examples

Basic results

CSS.escape(".foo#bar")        // "\.foo\#bar"
CSS.escape("()[]{}")          // "\(\)\[\]\{\}"
CSS.escape('--a')             // "--a"
CSS.escape(0)                 // "\30 ", the Unicode code point of '0' is 30
CSS.escape('\0')              // "\ufffd", the Unicode REPLACEMENT CHARACTER

In context uses

To escape a string for use as part of a selector, the escape() method can be used:

var element = document.querySelector('#' + CSS.escape(id) + ' > img');

The escape() method can also be used for escaping strings, although it escapes characters that don't strictly need to be escaped:

var element = document.querySelector('a[href="#' + CSS.escape(fragment) + '"]');
